Title: Improvements in or relating to freewheel clutches
IPC: F16D41/08
Filed: 1957-08-13
Abstract: 857,520. Freewheel clutches. REGIE NATIONALE DES USINES RENAULT. Aug. 13, 1957 [Aug. 17, 1956]. No. 25576/57. Class 80 (2). A freewheel clutch capable of transmitting drive in both directions and of acting as a freewheel when a member is held in an intermediate position has withdrawable spring stops associated with one element of the clutch to hold the member against movement to release the clutch, on withdrawal of the stops, it being possible to lock the clutch in either direction. A friction roller clutch has a cylindrical outer portion 1 and a polygonal inner element 2 with rollers 3 therebetween held in a cage 4 having angular freedom. The cage 4 is in frictional contact with the portion 1 at 1a and an integral flange 4a. Bores 5 in the polygonal element 2 contain pistons 6, lightly loaded by springs 7, having convex heads 9 and necks 10. Coaxial bores in the flange 4a house pushers 12 having bases 16 and studs 17 urged apart by springs 18 stronger than the springs 7, the studs 17 being engageable by an axially slidable control member 19. Under conditions when the control member 19 is away from cage 4, as shown in Fig. 3, the pistons 6 project from a retaining plate 8 into recesses 13 in the cage 4 and the cage is permitted sufficient angular movement to allow the freewheel being engaged for positive drive. Movement of the control member 19 towards the cage 4. causes telescoping of the studs 17 within the pusher 12 and the freewheel continues to drive. Reversal of rotation to allow freewheeling causes an edge 15 of a disc 14 rigid with the cage 4 to engage behind the head 9 of the piston 6 and freewheeling continues, the engagement preventing a return to positive drive while the elements are rotating at different speeds. If the relative direction of rotation change, thereby engaging the freewheel, the head 10 will be released and the piston urged into its housing by spring 18, allowing relative rotation of the cage 4 to engage the drive in either direction.

Filed: 1957-08-13
Abstract: 836,467. Electric selective signalling. ERICSSON TELEPHONES Ltd. Aug. 13, 1958 [Aug. 13, 1957], No. 25579/57. Class 40 (1). [Also in Group XXXIX] In a binary-decimal converter, vertical leads connected to binary input terminals I51 ... I54 are connected according to the binary code via rectifiers to horizontal leads P51 ... P50 indicative of the decimal digit, the leads being pulsed sequentially in such a manner that leads connected to more rectifiers are pulsed sooner than leads connected to less rectifiers. Thus assuming that binary inputs are present on I51, I52, 153, rectifiers X1, X2, X3 are back-biased and pulse P51 fires tube V51 to give an output on lead 051 indicative of digit 7. The resulting rise of potential over common cathode resistor R510 fires tube V500 and the resulting drop in anode potential is communicated to the triggers of the remaining tubes V52 ... V50 so that the subsequently occurring pulses P52, P53, P55, P57, P58, P59 cannot fire their associated tubes. The lock-out circuit may also be used in selection arrangements for automatic telephone exchanges (see Group XXXIX).

Title: Improvements in or relating to advertising apparatus
IPC: G09F11/23
Filed: 1922-09-21
Abstract: 208,762. Gower, J. F. Sept. 21, 1922. Forms and models with characteristic movements; actuating.-A poster, showcard, or the equivalent comprises a plane surface to which are pivoted flat representations of objects to which motion is imparted by compressed air or a solenoid or both. When air is employed it may be compressed by a pump driven by an electric motor and stored in a cylinder connected to the moving members by suitable pipes controlled by a distributing valve 119, Fig. 8. The valve distributes the air in turn to various cylinders containing reciprocating pistons, being rotated for this purpose by an adjustably mounted gear wheel 22 which may be driven by the air-pump motor. Fig. 2 shows pivoted objects 8, 9 guided by a slot 10 and raised by a lever 12 connected to a piston-rod 13 the cylinder 14 of which is connected by a tube 16 to the valve 119. The arm 8 falls by gravity and stops may be provided so that it falls with intermittent motion. The objects 8, 9 are mounted on a part 2 located behind a stationary front 1 and lifted into view by a piston-rod 30 working in a cylinder 31. The part 2 may fall by gravity or by the creation of a reduced pressure under the piston. Representations of the flaps 34, 35 of a packet 4 may be given an outward movement, or a picture with wording may be raised from behind a screen. Fig. 5 shows the representation of a child 38 which by means of air cylinders 65, 66 is given a movement in two directions, either alternately or with a movement in one direction taking place between every two movements in the other direction. Mechanism for effecting this latter motion is shown in dotted lines, and consists of a series of pivoted cams 72 - - 76. The first cam 72 is held by a spring 90 and its position determines which of the slots 70, 71 a pin 69 supporting the child 38 shall follow. Movement along the slot 70 actuates the cam 76, which throws the cam 72 over so that the next movement of the pin 69 will be along the slot 71. The first movement of the pin 69 in the slot 71 steps up the cam 74 one notch, and the second movement steps it up another notch, through the medium of cam 73, and by bringing its nose 89 against the spring 90 moves the cam 72 back again. The levers connecting the pistons of the air cylinders with the moving parts may be counterweighted and be adjustable. The representations may be outlined by lamps, and illuminating lamps may be switched on or off or be colour-screened bv the movement of the parts. The compressed air may also be utilized for producing sounds. According to the Provisional Specification, the moving parts of the poster &c. may be actuated hydraulically.

Abstract: 654,076. Lamp changing apparatus. WALLACE & TIERNAN PRODUCTS, Inc. Sept. 25, 1947, No. 26025. Convention date, Oct. 5, 1946. [Class 75(iv)] In a lamp-changing apparatus having a plurality of electric lamps carried by a rotary lamp carrier 7 mounted on and movable with respect to a stationary support 5, operating means responsive to the rotation of the lamp carrier move the lamps both in, and laterally with respect to, the plane of rotation of said lamp carrier, lamp support mountings 12 being pivoted to the lamp carrier 7 about axes parallel to the axis of rotation of said carrier, and each lamp being carried on a base 18 pivoted to one of said support mountings so as to allow relative movement between the lamps respectively and the lamp carrier in a direction normal to the plane of rotation of the carrier. Fig. 2 shows the lamp carrier 7 mounted for rotation about a stud 6 which is fixed at one end to the stationary support 5 and carries twin ring gears 13 splined on its outer end. Two lamp support mountings 12 fixed to gears 14 having the same number of teeth as the gears 13, are mounted for rotation about studs 10 fixed one at each end of the carrier 7. and idler gears 16 engage the gears 13, 14 so that on rotation of the carrier 7 the support mountings 12 will be maintained horizontal throughout. Two lamps 3, 4 are each mounted on a base 18 pivoted at one end between upturned ears 17 of the respective support mounting 12, the other end of the base 18 having an extension 23 providing a balljoint housing for one end of a link 22. The other end of the link 22 is secured to a swivel member 21 rotatable in the outer end of a crank 20 rigidly carried by the outer end of the stud 10 so that on rotation of the carrier 7 the rotation of the support mountings 12 about the studs 10 will cause an outward tilting of each lamp 3, 4 as it moves away from the operative position (shown by lamp 3), where it is held vertical. Fig. 3 shows an alternative arrangement wherein a cam or eccentric 27 is removably secured on the end of each stud 10 and arranged to bear on a hardened surface 28 integral with the base 18, tension springs 32 serving to hold the surfaces 28 in engagement with the cams 27.

Title: Improvements in honing or lapping machines
IPC: B24B33/02
Filed: 1939-09-19
Abstract: 532,651. Honing machine. BURGESS. A. F. (Barnes Drill Co.). Sept. 19. 1939. No. 26139. [Class 60] In a honing or lapping machine having a slide 9 reciprocated horizontally by cables 21, 22 these are tensioned by power-actuated means, such as a fluid pressure cylinder 31, and levers 36, 27 pivoted respectively at 37 and 28. As the cable 22 is under greater tension than 21 when the slide is moving to the left and the reverse when moving to the right the piston rod 35 is caused to act more strongly, so as to overcome the greater pull of the cable 22 and take up slack in the cable 21 when the slide is moving to the left. A drum 23, to which the cables are connected, is driven by a reversible hydraulic motor 26, Fig. 4, supplied through a valve 46 controlled by a valve 50 operated by the slide 9. With the valves in the position shown fluid from the pump 41 is supplied to the motor by a pipe 47 and exhausted by a pipe 47a, the slide 9 moving to the left. The left-hand end of the cylinder 31 is permanently connected to the pressure supply by a pipe 51 and the right-hand end to the pipe 47a so that, when the slide is moving to the left, the full pressure acts on the tensioning device but, when the slide is moving to the right, the pressure fluid is also admitted to the right-hand end of the cylinder and by acting on the smaller face of the piston 34 reduces the tensioning effect to an amount sufficient to take up slack in the idle cable 22. If resistance to the movement of the slide occurs the pressure in the supply pipe 44 increases so that a greater pressure acts on the tensioning device. Specification 478,290 is referred to.

Filed: 1976-04-26
Abstract: 1478723 Signal distributing systems MARCONI CO Ltd 26 April 1976 [21 June 1975] 26478/75 Heading H1 [Also in Division H4] A signal routing and selective phase-shifting system comprises a matrix of four 3db couplers 1, 2, 3, 4 of the asymmetric kind, arranged as two input couplers 3, 4 and two output couplers 1, 2, the two output ports of each input coupler being connected to respective input ports of each of the output couplers by connections 21, 22, 23, 24, the phase-shifts inherent in three of these connections (21, 23, 24) being nominally zero, and that of the fourth connection (22) being nominally 90 degrees. An asymmetric coupler is one in which the outputs are in phase when a signal is applied to one of the input ports and have a phase difference of 180 degrees when a signal is applied to the other input port. A waveguide magic-T junction has this property when the E and H arms are used as input ports and the geometrically symmetrical arms as output ports. Other alternatives are the "rat-race" ring hybrid and a modification of the quadrature branch coupler in which 90 degree phase-shifters are incorporated respectively in one of the input lines and one of the output lines. The connections 21, 22, 23, 24 may be waveguides or transmission lines. The phase-shifts available at the different outputs for signals applied to a particular input may be deduced from Fig. 1 and are described with respect to Figs. 5 to 8 (not shown). In particular, zero phase-shift is obtained at all four output ports when the signal is applied to input 12. Two such 4 Î 4 (Fig. 1) matrices may be connected to four 3db input couplers such that the four inputs of one matrix are connected respectively to first output terminals of the 3db couplers and the four inputs of the other matrix to the second output terminals. The connections to the first matrix have nominally zero phaseshift ; the connections to the second matrix have respective phase shifts of 3#/4, #/4, #/2 and zero (see Fig. 9, not shown). The arrangement shown in Fig. 10 uses eight 4 Î 4 (Fig. 1) matrices having phase-shifts in the connections which are multiples (shown circled) of #/8.

Title: Improvements in or relating to diazonium compounds
IPC: G03C1/54
Filed: 1954-09-14
Abstract: Substantially water-insoluble diazonium compounds are prepared by mixing a water-soluble diazonium compound with a finely divided water-insoluble particulate substance carrying groups capable of cation exchange.  Specified particulate substances are synthetic resins such as sulphonated phenolic, polycarboxylic, sulphonated polystyrene and polymethacrylic resins and synthetic or naturally occurring aluminium silicates, such as hydrogen aluminium silicate. In examples an aqueous solution of N : N - diethylamino - benzene - p - diazonium chloride (as the zinc chloride double salt) or diphenylamino-4-diazonium acid sulphate and citric acid is mixed with a slurry of "Wilkinite" (a natural clay) or with a powdered sulphonated polystyrene resin, the mixture is filtered, the cake is washed with aqueous citric acid and water and then either dried over potassium hydroxide and ground or made into an aqueous suspension. Analysis of the products shows that the particulate substances absorb the diazonium compound.  The borofluoride of the diazonium base may be used instead of the zinc chloride double salt in the above process.
